Excerpt: The RX1 is a fabulous piece of engineering excellence. Period. I'm not going to write an a-z review of it as there are many of those out there. I would like to comment on specifics, preconceptions, thoughts, observations, etc. Size and handling: It's not that small, but it's all relative! If you're coming from DSLR background then it will feel very small, but coming from RX100's and Nex 5n it feels "chunky". Solid, hefty. Nice to use, very nice.
Excerpt: I had the privilege of comparing the RX1 to the Sony A7 & A7R, Olympus OMD EM-1 and the FujiFilm X-T1. All of these cameras are wonderful but they just don't measure up to the RX1 in terms of edge to edge sharpness. The 55/1.8 on the Sony A7 comes very close but the RX1 still wins out. However, if I was just shooting portraits the A7R/A7 with the 55/1.8 is tough to beat.
Pros: Good in Low Light, Great Resolution, Large Clear LCD, Sharpness, Small / Compact
Summary: It's a great camera with a mostly fantastic build quality. I won't dwell too much on the many things I love about this camera, it's been well covered in these reviews already. Suffice it to say the lens and the sensor are expertly matched. I've never had pictures that correlate so closely to my mind's eye, to my memories of scenes and events past. They say the eye sees somewhere around 45mm, but I'm almost certain the heart and mind remember everything in 35.
Summary: I like leaf shutters. This one is very quiet and is welcome for taking pictures in harsh light using flash to produce acceptable results. I had been using a Fuji x100s and xPro1 but was disappointed with some of the images. This camera takes much better pictures for me. A RRS grip and base plate improve the handling and sticky filters help with white balancing the flash. I especially like the pictures that it takes of people, flowers and sunsets.
Summary: I rented this camera (Sony RX1r) for a week from borrowlenses.com. After that week, I fell in love with the camera. A couple of weeks later, my friend convinced me to get the Sony A7 with the Zeiss F2.8 lens. When I walked into Best Buy, I bought the Sony RX1r with the intention of returning the camera while I shopped around for two weeks for a great price on the Sony A7. It's been over two months since I walked into Best Buy to purchase a camera.
Summary: I owned - Fuji F30 Canon S95 Canon T3i Nikon D9000 D90 etc. I sold all my Nikon kit to move onto RX1. Best lens + body combination for a full frame camera. At the end of the day, the best camera is the one you have with you. I would carry my RX1 in places where I could never carry my D9000 + Sigma Art 35mm lens. Some may ask themselves if it is worth the money? My response, good pictures are intended to last a lifetime. The rest (price, AF, HD, zoom, etc.) are secondary.
Summary: For years I have been a point and shoot guy. I don't like DSLRs because I don't like to carry them. So this was a compromise. Larger package- but full frame. When you pick it up, the love affair begins. It is something I will keep, like I would a leica, in spite of going obsolete eventually. The pictures I take with it are amazing. The wide format does not make people look extra amazing unless you stand back- or they are model-skinny.
Summary: I used to be one of those guys that carried a Canon MkII. I got tired of lugging all that gear around so I decided that I would try the Sony RX1. What a revelation. Build quality is exemplary, photo quality is excellent, as are control placement and customizability. The Zeiss lens is truly excellent, and having a full-frame 24MP camera that can fit in a coat pocket and go almost anywhere without being an encumbrance makes this camera greatly appealing.
